For professionals in the chemical and manufacturing industries, understanding the precise technical specifications of raw materials is non-negotiable. Basic Blue 11, a critical dye for various applications, requires careful consideration of its properties to ensure optimal performance in end products. This article provides a detailed overview of the key technical specifications for Basic Blue 11 (CAS 2185-86-6), offering essential information for procurement managers, formulation chemists, and production engineers seeking to buy this dye.

Chemical Identity and Purity

Basic Blue 11, also known as Victoria Blue R or C.I. Basic Blue 11, carries the CAS number 2185-86-6. Its molecular formula is C29H32ClN3, with a molecular weight of approximately 458.04 g/mol. The most critical specification for most industrial applications is purity. Leading manufacturers, including ourselves, typically offer Basic Blue 11 with a minimum assay of 99.0%. This high level of purity is crucial for achieving vibrant, consistent shades and ensuring predictable performance in dyeing and coloring processes. Any impurities can lead to duller colors, reduced dye strength, or unwanted side effects in the final product.

Solubility and Physical Properties

The physical form of Basic Blue 11 is generally a blue-gray or red-brown powder. Its solubility characteristics are vital for its application. It exhibits good solubility in water, particularly hot water, turning the solution blue. It is also soluble in alcohol. These solubility profiles determine its suitability for various application methods, from aqueous dye baths in textile manufacturing to solvent-based systems for inks or wood stains. Understanding these properties helps formulators select the right application medium and concentration for their specific product.

Color Fastness and Application Suitability

When considering the durability of color, fastness properties are paramount. Basic Blue 11 typically offers a light fastness rating of 5-7 (on a scale of 1-8), indicating good to very good resistance to fading when exposed to light. Its fastness to perspiration and soaping is also important for textile applications, ensuring that the color remains stable during washing and general use. These properties make Basic Blue 11 a reliable choice for applications demanding longevity. If you are looking to purchase Basic Blue 11 for such demanding uses, sourcing from a reputable manufacturer in China that provides detailed technical data sheets is highly recommended. We pride ourselves on being a trusted supplier, offering consistent quality that meets these critical technical requirements.
